Definitions

  • the present invention relates to a fluid substance dispensing device.
  • it refers to a device for dispensing a fluid substance of a preferably creamy type, dispensed by means of a manually operated pump.
  • Another drawback is linked to the possibility that when the cream or creamy substance comes into contact with the air and remains unused for a long time, the said cream or creamy substances dries up, blocking the dispensing outlet with the plug formed thereby, which makes subsequent dispensing difficult.
  • the object of the present invention is to provide a fluid substance dispensing device which is improved compared with those according to the prior art.
  • a further object of the invention is to provide a dispensing device which is simpler and less expensive than those according to the prior art.
  • a still further object of the present invention is to provide a dispensing device which is less complex, and therefore more reliable, than commonly known devices.
  • reference number 1 is used to denote, as a whole, a fluid substance dispensing device.
  • the device 1 for dispensing a fluid substance S comprises a manually operated pump 2.
  • 'fluid substance S' means an essentially dense fluid substance, such as a cream, a soap, or a cosmetic fluid for make-up or a medical fluid.
  • the pump 2 is equipped with a hollow stem 3 for operation and moves against a spring 4.
  • the hollow stem 3 is coupled, for the movement thereof, with a piston 5 which slides in a sealed manner inside a cup-shaped body 6 so as to define a compression chamber 7 coupled with a first valve element 8 for the inlet of the fluid substance S into the compression chamber 7.
  • the first valve element 8 may be arranged on a bottom of the compression chamber 7 and intercepts a passageway which may be coupled with a dip tube T (if necessary). If the pump is coupled with an airless type deformable bag, the dip tube may not be present.
  • the pump may be coupled with a container C in which the fluid substance S can be housed (freely or inside a deformable airless bag).
  • the compression chamber 7 is fluidly coupled with a second valve element 9 for the outlet of the fluid substance from the compression chamber 7.
  • the second valve element 9 comprises the piston 5, which slides along the stem to open or close a passageway for fluid 9A flowing into the cavity of the stem 5.
  • the stem 3 is formed of two parts which are mutually snap-fit coupled.
  • a dispensing button 10 mounted on the hollow stem 3A, at one of the free ends thereof, there is a dispensing button 10 equipped with a dispensing nozzle 11.
  • the dispensing button envisages at least one channel 10A for feeding the fluid substance to the nozzle 11, which essentially puts the cavity of the stem in communication with the said nozzle.
  • the nozzle 11 is formed of an essentially rigid body 12 which snap-couples in a sealed manner with a seat 10B in the dispenser button 10.
  • the rigid body 12 is coupled, so as to form the nozzle 11, with a deformable body 13 which defines a dispensing port L for the fluid substance S.
  • the deformable body 13 - at least in proximity of the dispensing port L - deforms (see the dashed lines in Figure 2 ), so as to allow constant dispensing of the fluid substance S through the port L.
  • the deformable body 13 returns to its non-deformed configuration, essentially closing up the dispensing port.
  • the deformable body can define a cross-shaped dispensing port L; the port may also be configured as a line segment or as a 'cut', etc.
  • the cross preferably has four arms, but configurations with three, five, six, eight arms etc. may also be envisaged.
  • the dispensing port L can allow a slight passageway for air between the channel 10A and the outside. In this way, at a first delivery, it is possible to 'bleed' the compression chamber 7 of the pump to remove the air present there (before the said chamber is filled with the substance S to be dispensed).
  • the term 'slight passageway for air' means that the port L envisages a slight possibility of air leakage.
  • the port L can be configured so as to allow the air from the dispensing channel to flow, but in such a way as to prevent the fluid substance S, which is denser than the air, dripping or running.
  • the deformable body 13 is coupled with the rigid body 12 by overmoulding, and therefore forms what is essentially a single piece therewith.
  • This technology makes it possible to mould a section of the component in a first step (for example the rigid body 12) and in a second step, to inject - by means of a movement inside the mould - a second section (13) onto the first, within in a single moulding process.
  • This technology makes it possible to create components consisting of a single piece but made of materials with different mechanical/physical characteristics.
  • the adhesion of the two parts is achieved by means of chemical adhesion between the two materials.
  • Mechanical anchorage systems may also be envisaged, which are essentially either protuberances or grooves 40 made on or in the surface of the rigid body 12, and therefore located at the interface between the rigid body and the deformable body.
  • the presence of the protuberances or grooves 40 which may have any conformation, increases the contact surface between the two over-moulded parts and creates undercuts intended to improve and stabilise the adhesion over time.
  • the rigid body 12 may be made of one or more of the following plastic materials: HDPE-PP-PA-SANTOPRENE -HYTREL-PBT.
  • the deformable body which - remember - can be overmoulded onto the rigid body, may advantageously be made of one or more of the following materials: LDPE-PA-SANTOPRENE -HYTREL-RUBBER.
  • the dispenser button 10 is advantageously made of: PP -PETG - ABS- PA.
  • the dispensing button 10 may be encased with a cover 20, for example made of metal or plastic with a glossy finish, etc.
  • the cover may be endowed with an opening 20A at the said nozzle 11.
  • the dispensing button 10 may feature, at the seat 10B, a cylindrical element 30 onto which the nozzle 11 is fitted (see Figure 2 for more information).
  • the cylindrical element is far or distant from the deformable body 13, allowing its free movement.
  • the nozzle 11 may feature centring ribs N on the cylindrical element 30.
  • a coupling of this kind minimises the risk of ovalisation of both the cylindrical element 30 and the rigid body 12 of the nozzle 11, making it possible in any case to machine-assemble the invention.
  • the nozzle 11, or rather the rigid body 12 may feature, on the outside, a protruding annular edge 31, which is coupled with the seat 10B in a sealed manner by interference fit. This allows the nozzle to be snap fitted into its seat.
  • the deformable body 13 may feature at least two but preferably four flexible blades 32, which define the dispensing port L.
  • the said flexible blades 32 may feature an inclined surface 33 converging towards the outside of the nozzle 11. This configuration benefits the deformation of the flexible blades when the substance S is dispensed and improves the 'cutting off' of a run of the substance S from the dispensing port.
  • the flexible blades 32 of the deformable body 12 in that part where the at least two flexible blades are mutually faced (directly), define the dispensing port L.
  • the described invention is simple to make and optimises the dispensing of creamy substances or substances with a certain density, minimising the possibility of runs and essentially 'protecting' a large part of the substance S left behind the nozzle 11 from the air and therefore minimising or eliminating the volume of this substance S which would otherwise dry up.
